I've waxed lyrical both on the podcast and on this blog about how much I love the conceit that in the Marvel universe, Marvel comics exist purely as a licensing entity, creating comics based on the real-life exploits of super-heroes. This panel is a very subtle example of Stan using the subtleties of this gimmick in his storytelling.

The original 'bathtub' Fantasticar has been replaced by the sleeker, more modular incarnation, and on his way down to New Mexico, Reed can't help showing it off to General Ross. However, he's not giving away the speed, oh no - he's even dropped a line to Marvel Comics to ask them not to mention just how fast The Fantasticar goes, hence this rather esoteric and wonderful editor's note.
